A Colorado man arrested two weeks ago in connection with a triple homicide near Forestville has been booked into Sonoma County Jail and will make his first court appearance Tuesday.

Mark William Cappello, 46, had been jailed in Mobile, Ala., after his Valentine's Day arrest in the Feb. 5 slayings in which three men were shot and killed during a marijuana deal.

The victims included a Sebastopol native, Raleigh Butler, 24, and Todd Klarkowski, 42, of Boulder, Colo., who reportedly brought Cappello in on the deal.

Sheriff's Lt. Dennis O'Leary said Friday that investigators believe Klarkowski, and the third victim, New York resident Richard Lewin, 46, had been partners in interstate marijuana trade for some years and that Klarkowski and Cappello also were associates.

O'Leary, who oversees sheriff's investigations, said Cappello in turn involved his friend, Odin Leonard Dwyer, a Denver-area resident.

Dwyer, 38, and his father, Francis R. Dwyer, 65, were arrested earlier this week in Colorado and New Mexico, respectively.

O'Leary said surveillance photos from gas stations in Nevada and Wyoming indicate the father and son traveled to Sonoma County with Cappello in the days leading up to the killings. They are believed to share responsibility for the killings, O'Leary said, and have been arrested on suspicion of murder.

Cappello is a resident of Central City, Colo., a historic mining community outside Denver. He was tracked to the southern gulf coast after the slayings and was arrested when Mobile County, Ala., deputies stopped him for a traffic violation on Interstate 10 and learned a stop-and-hold order had been issued by Sonoma County.

Jail records indicate he was booked into the Sonoma County Jail just after midnight Thursday, although jail personnel had not acknowledged his presence as of late Friday afternoon. He is being held without bail on three counts of suspected murder and is scheduled to be in court at 1:30 p.m. Tuesday, jail personnel said Saturday.

Odin Dwyer was arrested early Tuesday morning at a residence outside Denver and was being held in a detention center pending extradition to Sonoma County, O'Leary said.

His father was arrested at about the same time at an RV park in Truth or Consequences, N.M., and was awaiting extradition there, authorities said.
